Hi Everyone!

I have some doubts! I hope you can help me.
Currently, I´m doing an arc-flash study using ETAP software, but, I´ve notice that ETAP has a feature that allow us to provide one or two configurations for the electrodes, so, my doubt is:

1. If you have a Switchboard and the first configuration I mean electrode line side is VCBB until main CB (that is my firt configuration?) and load side of the main CB is VCB arrangement (that is my second configuration)?

2. After the main CB with VCB arrengment there is a change of the configuration I mean, the busbar configuration change to HCB, so, the main bus must be configurated as HCB and the enclosure configuration of the main CB must be VCBB - main CB - VCB?

I share with you a screenshot of this feature.

I would really appreciate your feedback and comments.

Thank you in advance!
